TECHNICAL FIELD

The application relates to a method for producing a floorboard which hasa carrier plate and a topside veneer.

BACKGROUND

Floorboards with a top or cover layer of real wood are in particularused as real wood floors or parquet floors. Such floors provide anatural living atmosphere. They are pleasantly warm when walking on itand compensate humidity fluctuations in the room air, which contributesto a healthy room atmosphere. Also, floorboards with a top or coverlayer made of cork or a cork veneer are very popular.

A method for producing parquet or veneer floorboards with a cover layerof real wood is described in DE 102 45 914 A1. There a cover layer ofreal wood is impregnated with thermoset synthetic resins. After theimpregnation the cover layer is glued to the carrier plate. The coverlayer is also printed on.

Common are floor panels with a three-layer construction and profiledjoining surfaces at the side borders for forming joining means in theform of groove and tongue or a so-called click system. The joining meansenable a mechanical coupling of the individual panels with each other ina floor cover or a wall or ceiling covering. The carrier plate isusually made of a wood material, in particular a highlight compressedfiber plate (HDF). The topside cover layer of real wood can be ofdifferent thickness. When the cover layer of wood has a thickness ofmore than 2.5 mm there is a parquet floor. According to a commonterminology used in the art veneers for cover layers of floor panelsstart at about 0.4 mm. generally floor panels with wood cover layers ofsmaller than 2.5 mm are referred to as real wood or veneer floors.

After the gluing on the veneer, flaws in the surface, for example branchholes or cracks, are smoothened over. Usually, an excess of smootheningcompound is used which excess is then removed again later. This isusually performed by grinding or brushing. In particular, in the of thinveneer layers this involves the risk that the layer is damaged by thesubsequent mechanical processing. For this reason, oftentimes veneersare used that are thicker to begin with or veneers that have flaws aresorted out beforehand. However, this is uneconomical and leads to thefact that the variability of the optical appearance of the natural woodfloors is diminished.

Also known is a so-called real wood laminate. In this case an overlay isapplied to the cover layer made of veneer for example in the form of amelamine paper or melamine film. Subsequently this sandwich is thenpressed. A disadvantage is that the flaws naturally occurring in thisproduct such as gaps cracks branches or pores often appear milky. Thecause for this is the missing or insufficient pressing pressure duringthe pressing process because in the region of the flaws the counterpressure is absent. On the other hand, when a higher pressure is appliedthe structure of the press plate dominates the wood surface and thenatural wood structure or appearance suffers.

SUMMARY

Based on the state of the art the application is based on the object toprovide an efficient method for producing floorboards with a topsideveneer, which saves material and costs.

The object is solved with a method for producing a floorboard having atopside veneer, said method comprising: forming a multilayer bodycomprising a starting carrier plate, a plurality of veneers placed onthe starting carrier plate so that a gap is formed between neighboringones of the veneers, a resin layer comprising a resin provided betweenthe starting carrier plate and the veneers, and a balancing layerarranged on a bottom side of the starting carrier plate; joining thestarting carrier plate, the resin layer, the veneers and the balancinglayer by pressing the multilayer body in a press; separating themultilayer body into individual boards between the neighboring veneersin a region of the gap; profiling the individual boards at side bordersof the boards; and providing the individual boards with joining means.

Advantageous embodiments and aspects of the application are set forthherein.

The present application relates to a method for producing a floorboard,which has a carrier plate and a topside veneer. The application inparticular relates to the production of real wood or veneer floor boardswith a veneer of wood and a thickness of the veneer of smaller than 2.5mm in particular with a thickness between 0.6 mm and 1.2 mm. the veneercan also be a cork veneer in particular a cork oak veneer.

The method according to the application is characterized by thefollowing steps:

providing a large area starting carrier plate;

providing a number of veneers;

forming a multi-layer body form the starting carrier plate and theveneers and a resin layer provided between the starting carrier plateand the veneers, wherein neighboring veneers are positioned spaced apartrelative to each other on the starting carrier plate so that a gap isformed, and a balancing layer arranged on a bottom side of the startingcarrier plate;

connecting the starting carrier plate, resin layer and veneers and thebalancing layer by pressing the multilayer body in a press;

subsequently separating the pressed multilayer body into individualboards, wherein the separation is preformed in the region of a gapbetween two neighboring veneers and

the boards are profiled at their side borders and are provided withconnecting means.

The pressing process in which the layers of the multilayer body arepressed with each other and connected, is performed with the followingprocess parameters:

the pressing pressure is greater or equal to 1,000 kilopascals (kPa),preferably greater than or equal to 3,500 kilo Pascal (kPA)

the pressing temperature is grater or equal to 100° C., in particulargreater or equal to 120° C. and is preferably in the temperature rangebetween 180° C. and 120° C.

the pressing time is between 10 and 60 seconds.

During the pressing of the multilayer body the resin of the resin layeris plasticized under the influence of heat and cured. By means of theresin the starting carrier plate and the wood veneers are glued to eachother. Further the gaps between the veneers are filled with resin.

For producing a floorboard according to the application a large surfacestarting carrier plate is provided. A large area carrier plate meansthat it has a size in length and width which corresponds to a multiple,in particular an integer multiples of the size of one floor board.

The starting carrier plate and thus the carrier plate of a floor boardis a plate material made of a wood material, such as solid wood,chipboard, wood fiver material, MDF (Medium Density Fiber Board) or HDF(High Density Fiber Board). Within the scope of the applicationpreferably a carrier plate made of HDF is used. Also conceivable arecarrier plates made of waterproof materials for example in the basis ofmineral materials such as fiber cement, sand-bindegemische or woodplastic composite materials (wood-plastic-composites WPC) and wood fiberpolymer composite materials or also the use of magnesite plates. Anaspect is here directed towards the use of natural fiber reinforcedplastic as work material for the carrier plate or the basis carrierplate. Beside wood fibers also other plant fibers such as Jute or Flaxcan be used in particular in a wood fiber or wood powder proportion of50% to 90% and a plastic matrix of polypropylene (PP). further a woodplastic composite on the basis of thermoplastically processiblethermoset which contain modified melamine resin with natural fiber ornatural powder proportion find use. In this connection, bamboo plasticcomposites (BPC) also offer interesting practical approaches. In thismaterial bamboo fibers or bamboo powder are used as natural material.

As mentioned above, also plates on the basis of cement containingbinders or fiber cement plates can be used as carrier plate. Also, likemagnesite plates. Magnesite plates are made of a mixture of magnesiumoxide, calcium carbonate, silicates, and fibers, in particular woodand/or glass fibers. An advantage of magnesite plates is the low weightand the low heat conducting capacity as wells as their flame resistance.Magnesite plates are categorized as non-flammable.

The starting point of the production of the floorboards according to theapplication is a large-area carrier plate, in the present case referredto as starting carrier plate. Such a large-area starting carrier plateis rectangular and has a size of 2,000 mm to 5,000 mm in length and1,200 mm to 2,100 mm in width. Usually, the carrier plate or thestarting carrier plate has a thickness of 4.5 mm to 12 mm.

An aspect of the application is that a resin layer is provided betweenthe carrier plate and the veneer and the carrier plate, the resin layerand the veneer are pressed together and are joined to each other. Theveneers are hereby positioned on the carrier plate with a lateraldistance to each other so that a gap is formed between the veneers. Theveneer is permeated or infiltrated by the resin of the resin layer. Thepressing is conducted hot at a temperature of more than 100° C., morethan 120° C., preferably at a temperature between 180° C. and 210° C.The pressing temperature relates to the temperature at the press plateof the press. This temperature is also present at the contact surfacesbetween the press plate and the topside of the veneer or the bottom sideof the carrier plate.

The resin layer is made of a resin. This is in particular a thermosetsynthetic resin. Colored or transparent melamine resins ormelamine/polyurethane mixtures can be used. An aspect of the applicationis directed towards using resins, which cure or react under theinfluence of heat and pressure. In this connection aminoplastic,thermoset or reactive resins such as polyurethane (PUR) or thermoplasticPolyurethane can be used. The resin can be present on a paper-typecarrier in the form of a paper impregnate, also referred to as resinlayer. The resin or the resin layer can further be present or configuredas resin film.

The veneers are provided as strips or plates. The veneers are positionedon the starting carrier plate with a lateral distance to each other sothat a gap is formed. Hereby the veneers are arranged or positioned sothat continuous gaps are created that extend along a longitudinaldirection of the starting carrier plate and are spaced apart by a widthcorresponding to a floorboard to be separated. A multilayer body isformed including the starting carrier plate and the veneers. Between thestarting carrier plate and the veneers, a resin layer is incorporated.On the bottom side of the starting carrier plate a balancing layer isarranged. The thusly formed multilayer body is then pressed in a pressso that the starting carrier plate, the resin layer and the veneers andthe balancing layer are joined. The pressing of the multilayer body ispreformed in a press, i.e., at a pressing pressure of greater or equalto 1,000 Kilopascal (kPa). Preferably the pressing pressure is above3,500 Kilopascal (kPa). The pressing temperature is greater or equal to100° C., in particular greater than or equal to 120° C. Preferably thepressing temperature is between 180° C. and 120° C. The pressingtemperature is in relation to the temperature at the pressing plate orthe press. Within the framework of the method according to theapplication the pressing time in chi the multilayer body is impingedwith pressure in the pressing tool is between 10 seconds and 60 seconds.

During the pressing process the surface of the veneers may be providedwith a texture, a pattern or ornaments by a textured plate or atexturizer. Subregions of the texture may vary regarding glossiness. Thetexture may also have different depth. The depth of the texture can beup to 0.6 mm. Relative to the veneer thickness the texture can have adepth of ⅔ of the thickness of the veneer.

After the pressing process the pressed multilayer body is separated intoindividual boards. The separation of the multilayer body into individualboards is carried out in the region of a gap between two neighboringveneers. The separation occurs thus between two boards in the gap whichis filled with the cured resin, and which extends over the length of thestarting carrier plate. The width of the individual veneers is adjustedto the width of the individual floorboard.

The division of the pressed multilayer body is performed after cooling.For this purpose, the multilayer body can be transported over a coolingpath or can be intermediately stored for cooling.

In a subsequent work step the individual boards are profiled at theirside borders. The profiling is only performed after the carrier platehas cooled to room temperature. The profiling serves in particular forforming joining means at the longitudinal and transverse sides of thepanels.

During the profiling the remainder of the gap, which extends as borderstrip made of resin along a floorboard, can be completely removed.Further it is possible that a border strip made of resin remains alongthe side borders of the veneer. The side borders made of resin form avisual contrast to the veneer. In addition, the border strip isadvantageous during the mechanical processing of the side borders.Because the side border regions of the boards are stabilized by theresin, a mechanical processing is advantageously possible. In particularfraying of the veneer can be avoided.

As pressing tool, in particular a shod-contact press, is used or acontinuous press. During the hot-pressing process or the pressingprocess under heat influence, the resin layer is plasticized andpenetrates into the veneer. An aspect of the application is that theresin of the resin layer permeates the veneer up to the topside of theveneer. This causes pores, cracks, gaps and/or other flaws in the veneerto be filled with resin during the pressing process. The resin of theresin layer forms an inseparable connection between the veneer and thecarrier plate. A particular advantage of the application is thus thattwo production steps, i.e., gluing and smoothening of the veneer areperformed in one step.

In particular the pressing of the multilayer body is performed so thatthe resin permeates the veneer and after the pressing the resin isvisible at the surface of the veneer. In this connection in particularresins that are color coordinated with the color of the veneer are used.In terms of production a black resin is regarded as universallyadvantageous. Suitably the pressing is performed so that no or only verylittle resin sticks to the surface of the veneer and with this thefloorboard. Pores, cracks, gaps, or other flows are visibly filled.However, no, or only very little excess resin exits on the surface. Thepressed product then only has to be texture-brushed and may be providedwith a surface oil treatment or varnishing.

Within the framework of the application, the resin layer can be formedby a resin paper. The resin paper is made of a paper with a paper weightof 30 g/m.sup.2 up to 120 g/m.sup.2. This paper is soaked with resin andhas then at least twice or three times the weight, preferably the resinpaper has a weight of more than 100 g/m.sup.2. The resin paper is thus apaper impregnate with a strong excess of resin. The resin paper isintegrated between the starting carrier layer and the veneers. For thisthe products are joined layer by layer including the balancing layer.Subsequently the multilayer body is pressed.

An alternative provides that the resin layer is formed by a resin filmthat is applied on the topside of the starting carrier plate. Hereby theresin is applied to the starting carrier plate in liquid form and ispartially dried or pre-condensed. The resin film adheres to the startingcarrier plate as a gel or wax-like layer.

The resin layer can also be formed on the bottom side of the veneers inthe form of a resin film. Also, in this case the resin is applied inliquid form on a side of the veneers. As a result, the veneers areimpregnated with resin. The resin applied in liquid form is partiallydried and pre-condensed. The thus impregnated veneer provided with theresin layer is further processed after producing the resin layer. Priorto forming the multilayer body, the veneers are rotated so that theresin layer is on the bottom side of the veneers and comes into contactwith the topside of the starting carrier plate.

A resin film can also be formed by applying resin in powder form ontothe surface of the starting carrier plate or onto the veneers. Thepulverous resin is then melted under heat influence so that the resinfilm forms.

Generally the resin can also be present or processed paste-like, i.e.,in the form of a paste.

The amount of resin is dosed so that it infiltrates or permeates throughthe veneer, however it cannot exit onto the surface of the veneer as aresult of the closed press. The resin is pressed into and fills pores,flaws, cracks, or gaps in the veneer. The natural wood surface or corksurface and texture remains preserved. The resin can be thickened with afiller. As a result, more mass is present to fill pores, cracks, gapsand/or flaws. As filler organic or inorganic materials can be used, inparticular mineral pigments, stone powder, or chalk, as well as woodpowder or wood meal.

The balancing layer compensates tensions in the multilayer body. Thebalancing layer can be a veneer, a paper, a foil, or a film, inparticular a synthetic resin film. Advantageously a balancing veneer ora balancing paper is also provided with resin or is impregnated withsynthetic resin. The balancing layer is pressed during production of thefloorboards according to the application together with the startingcarrier plate, the veneers and the resin layer and connected on thebottom side with the starting carrier plate.

The floorboards are profiled at their side borders and are provided withjoining means. Joining means can be configured as groove and tongue.Preferably the side borders are provided with a click joint. The boardscan also be provided with a circumferential chamfer at their topsideborders. In the case of a floorboard with chamfer the intermediate resinlayer has a very positive effect on the humidity sealing in theinstalled product.

A color design of the floorboard is also possible when the resin isvisible at the side borders. In particular this is accomplished by acolored resin, which is color coordinated with the veneer. Herebyindividual or all side borders can be configured with a visible borderstrip of resin. A variance in optical design of a panel results when aresin is used that has a color that contrasts the color of the veneer.This for example allows generating a particular visual appearance of thejoints in a targeted manner. The interplay between resin and veneerenables visual accentuation of the surface of a floor-, wall- orceiling-panel according to the application. For this purpose, alsoeffect material can be used in the resin, as mentioned pigments andother fillers.

A further aspect is to form the chamfer as a decorative visuallydelimiting edge. Further the veneer can be printed with a decor.Preferably the printing is performed by means of digital printing.Hereby a system of printing inks is used that is adapted to the usedresins. It is possible to apply a sealing to the veneer. The termsealing means the application of color, a pickle or an oil or a varnishor varnish system.

It is particularly advantageous that the floorboard or the surface ofthe veneer can be subjected to a mechanical processing after thepressing. The surface treatment in particular includes grinding orbrushing of the surface. This allows accentuating the natural visualappearance of the surface. By unevenly treating the surface an agedstructure or look, a so-called vintage optic can be achieved. Thesurface of the boards can thus for example have a rough-sewn surface orchatter marks or grinding flaws or the like.

A floorboard produced with the method according to the application iscost-effective in manufacture and has a high quality. Particularlyadvantageous is that no large-area stitched or glued veneers have to beused that are adjusted to the dimensions of a starting carrier plate.The division of the starting carrier plate into individual floorboardsis performed along the gaps formed between the wood veneers.

The boards are compelling in their natural wood optic or cork optic witha rustic character due to the optically perceptible filled cracks, gapsand/or branch holes. Because the veneer, i.e., the topside wear surfaceor cover layer of the panel is permeated or impregnated with resin, inaddition the resistance, in particular impact resistance and wearresistance is increased. The increased resistance enables mechanicalprocessing of the veneer for example by grinding or brushing with alower risk of destroying the optic by the mechanical processing. Theboards are significantly more durable. Advantageously the applicationalso enables using softer woods or veneers made of softer woods such aslarch. As a result of the impregnation or permeation with resin a veneermade of a soft wood becomes harder and more durable.

Within the framework of the application also advantageously vapored orsmoked veneers can be used. Particularly suited are further veneers madeof coarse-pored woods such as oak, ash, larch, or spruce as well asveneers made of cork. The quality of the veneers is improved and theveneers are optically accentuated by the infiltration with resinaccording to the application.

DETAILED DESCRIPTION

For producing floorboards according to the application a multilayer bodyis formed. The multilayer body includes a large area starting carrierplate 1. The starting carrier plate 1 is shown in FIG. 1 . The startingcarrier plate 1 is configured rectangular. Common starting carrierplates 1 have a length between 2,000 mm to 5,600 mm and a width of 1,200mm to 2,100 mm. usually the starting carrier plate 1 has a thickness of4.5 mm to 12 mm. on the topside of the starting carrier plate 1 woodveneers 2, 3 are placed. On the bottom side of the starting carrierplate 1 a balancing layer, which is not shown in FIG. 1 , is providedbetween the starting carrier plate 1 and the wood veneers 2, 3 a resinlayer 4 made of resin 5 is provided. The resin 5 or the resin layer 4 isindicated schematically in FIG. 1 . The resin layer 4 extends twodimensionally over the starting carrier plate 1.

Onto the starting carrier plate 1 the individual wood veneers 2, 3 areplace as strips. The strips extend over the entire length of thestarting carrier plate 1 between the starting carrier plate 1 and theveneers 2, 3 the resin layer 4 of resin 4 is integrated (interposed).The resin is in particular a thermoset synthetic resin. The resin layer4 can be formed by a resin paper. As an alternative the resin layer 4 isformed by a resin film applied onto the topside of the starting carrierplate 1. The resin layer 4 can also be formed by a resin film applied tothe bottom side of the veneers 2, 3.

The individual veneers 2, 3 are spaced apart by a lateral distance a sothat a gap 6 is formed between. the individual veneers 2, 3. Asmentioned, on the bottom side of the starting carrier plate 1 thebalancing layer is arranged. A balancing layer 7 is shown in FIGS. 4 and5 . The starting carrier plate 1 with the placed veneers 2, 3 and theinterposed resin layer 4 and the balancing layer 7 form the multilayerbody. The multilayer body is placed in a pressing tool where it ispressed. The pressing pressure is greater or equal to 1,000 KPapreferably greater or equal to 3,500 KPa. The pressing temperature isgreater than or equal to 100° C., in particular greater than or equal to120° C. preferably the pressing temperature is between 180° C. and 210°C. the pressing time can be between 10 and 60 seconds.

FIG. 1 shows the multilayer body prior to the pressing. FIG. 2 shows themultilayer body after the pressing. During the pressing of themultilayer body the resin 5 of the resin layer 4 is plasticized underthe influence of heat and cured. By means of the resin 5 the startingcarrier plate 1 and the wood veneers 2, 3 are glued to each other.Further the gaps 6 between the veneers 2, 3 are filled with resin 5.Moreover, the resin infiltrates the wood veneers 2, 3. The resinpermeates the veneers 2, 3 up to their topside or surface 8. As aresult, pores, cracks, gaps and/or other flaws in the veneers 2, 3 arefilled with resin 5. The veneers 2, 3 are permeated with resin 5 so thatafter the pressing resin 5 is visible at the surface 8 of the veneers 2,3.

After the pressing the pressed multilayer body is separated intoindividual floorboards 9, 10. Individual floorboards 9, 10 are shown inFIG. 3 . The separation of the multilayer body into individualfloorboards 9, 10 is performed in the region of a respective gap 6between two neighboring veneers 2, 3. As an example two separation linesT1, T2 are indicated in FIG. 2 which extend over the length of thestarting carrier plate 1 respectively along a gap 6 that is filled withcured resin 5.

In a subsequent work step the side borders 11, 12 of the floorboards 9,10 are profiled. During the profiling the side borders 11, 12 areprovided with joining means 13, 14. Joining means 13, 14 can berecognized in FIGS. 4 and 5 . During the profiling the remainder of theborder strip 15, which extends along a floorboard 9, 10 as border strip15, 16 of resin 5, can be completely removed. It is also possible that aborder strip 15, 16 of resin 5 remains along the side borders 11, 12 ofthe veneers 2, 3.

The resin 5 can also be enriched with a filler. The surface of thefloorboards 9, 10 can also be printed with a decor. Also, the sideborders 11, 12 or the border strips 15, 16, which are made of hard resinmaterial, can be printed. The surface of the floorboards 9, 10 can beprovided with a sealing. Furthermore, the surface of the floorboards 9,10 can be subjected to a mechanical surface processing, in particular agrinding process and/or a brushing process and/or an embossing process.The aforementioned measures serve for optically accentuating andtexturizing the surface.

FIGS. 4 and 5 schematically illustrate the construction of thefloorboards 9, 10 produced according to the application in theirvertical plane. The Figures are not to be understood to be to scale.

Each floorboard 9, 10 has a carrier plate V, on the topside of which aveneer 2 or 3, i.e., a wood veneer is applied. The carrier plate V andthe wood veneer 2, 3 are pressed and glued to each other via a resinlayer 4 or resin. 5 over their entire surface. On the bottom side of thecarrier plate V the balancing layer 7 is provided. At the side borders11, 12 of the floorboards 9, 10 connecting means 13, 14 are provided inthe form of locking strips. In a floor cover of neighboring floorboards9, 10 the respective corresponding locking strips engage with eachother. In FIGS. 4 and 5 the locking strips are shown at two opposinglongitudinal sides of the floorboards 9, 10. The floorboards 9, 10 alsohave locking means at their respective head sides, which however are notshown here.

The carrier plate V and the topside wood veneer 2, 3 and the carrierplate V and the bottom side balancing layer 7 are thermally pressed witheach other and inseparably glued with each other. The gluing between thecarrier plate V and the wood veneer 2, 3 is accomplished via theinterposed resin 5. Also, the balancing layer 7 is glued with thecarrier plate V via a resin 5.

The floorboards 9, 10 are produced as described above. The individualfloorboards 9, 10 are separated from the pressed multilayer body. Herebythe multilayer body is separated along the gaps 6 which extend over theentire length.

As can be seen in FIG. 4 , in the floorboard 9 a border strip 16 made ofresin 5 or a residual gap that had remained after profiling of eh sideborders 11, 12 after the separation was removed. Wood veneer 2 and resinlayer 4 end flush with the upper face side 17 of the side borders 11,12.

In the floorboard 10 as shown in FIG. 5 , a border strip 15, 16 isformed at the side borders 11, 12 of the wood veneer 3. Thus, borderstrips 15, 15 are made of resin 5. The surface 18 of the border strips15, 16 extends in the plane of the surface 8 of the wood veneer 3.

As mentioned above during the production of the floorboards 9, 10 thestarting carrier plate 1 or the carrier plate V, the wood veneer 2, 3the balancing layer 7 with the interposed resin 5 are pressed to eachother under heat influence. During the pressing procedure the resin 5 isplasticized. The resin 5 present between the starting carrier plate 1and the wood veneer 2, 3 infiltrates the wood veneer 2, 3. Hereby theresin 5 can permeate the wood veneer 2, 3 up to the surface 8 of thewood veneer 2, 3. Pores, cracks, gaps, or other flaws in the wood veneerare filled with resin 5 during the pressing. A subsequent gluing of thewood veneer 2, 3 with the starting carrier plate 1 follows and thesmoothening of the surface 8 of the wood veneer 2, 3 together in onework step during pressing of the multiplayer body.
